1.1 New AP-5131 Features
With this most recent 1.1 release of the AP-5131 firmware, the following new features have been
introduced to the existing AP-5131 feature set:
• Mesh Networking
• Additional LAN Subnet
• On-board Radius Server Authentication
• Hotspot Support
• Routing Information Protocol (RIP)
• Manual Date and Time Settings
1.1.1 Mesh Networking
Utilize the AP-5131’s new mesh networking functionality to allow the AP-5131 to function as a bridge
to connect two Ethernet networks or as a repeater to extend your network’s coverage area without
additional cabling. The AP-5131 mesh networking functionality is configurable in two modes. It can
be set in a wireless client bridge mode and/or a wireless base bridge mode (which accepts
connections from client bridges). These two modes are not mutually exclusive.
In client bridge mode, the AP-5131 scans to find other access points using the selected WLAN’s
ESSID. The AP-5131 must go through the association and authentication process to establish a
wireless connection. The mesh networking association process is identical to the AP-5131’s MU
association process. Once the association/authentication process is complete, the wireless client
adds the connection as a port on its bridge module. This causes the AP-5131 (in client bridge mode)
to begin forwarding configuration packets to the base bridge. An AP-5131 in base bridge mode allows
the AP-5131 radio to accept client bridge connections.
The two bridges communicate using the Spanning Tree Protocol (STP). The spanning tree determines
the path to the root and detects if the current connection is part of a network loop with another
connection. Once the spanning tree converges, both access points begin learning which destinations
reside on which side of the network. This allows them to forward traffic intelligently.
After the AP-5131 (in client bridge mode) establishes at least one wireless connection, it will begin
beaconing and accepting wireless connections (if configured to support mobile users). If the AP-5131
is configured as both a client bridge and a base bridge, it begins accepting client bridge connections.
In this way, the mesh network builds itself over time and distance.
